Detailed Description

Official definition of the nifti1 header. Written by Bob Cox, SSCC, NIMH.

HISTORY:

29 Nov 2007 [rickr]

• added DT_RGBA32 and NIFTI_TYPE_RGBA32
• added NIFTI_INTENT codes: TIME_SERIES, NODE_INDEX, RGB_VECTOR, RGBA_VECTOR, SHAPE

Define Documentation

#define FPS_INTO_DIM_INFO( fd, pd, sd )

Initializer: ( ( ( ((char)(fd)) & 0x03) ) | \ ( ( ((char)(pd)) & 0x03) << 2 ) | \ ( ( ((char)(sd)) & 0x03) << 4 ) )

#define NIFTI_5TH_DIM( h )   ( ((h).dim[0]>4 && (h).dim[5]>1) ? (h).dim[5] : 0 )

Check if a nifti_1_header struct contains a 5th (vector) dimension. Returns size of 5th dimension if > 1, returns 0 otherwise.

#define NIFTI_INTENT_NONE   0

default: no intention is indicated in the header.

#define NIFTI_NEEDS_SWAP( h )   ( (h).dim[0] < 0 || (h).dim[0] > 7 )

Check if a nifti_1_header struct needs to be byte swapped. Returns 1 if it needs to be swapped, 0 if it does not.

#define NIFTI_ONEFILE( h )   ( (h).magic[1] == '+' )

Check if a nifti_1_header struct says if the data is stored in the same file or in a separate file. Returns 1 if the data is in the same file as the header, 0 if it is not.

#define NIFTI_VERSION( h )

Initializer: \ ( ( (h).magic[0]=='n' && (h).magic[3]=='\0' && \ ( (h).magic[1]=='i' || (h).magic[1]=='+' ) && \ ( (h).magic[2]>='1' && (h).magic[2]<='9' ) ) \ ? (h).magic[2]-'0' : 0 ) Given a nifti_1_header struct, check if it has a good magic number. Returns NIFTI version number (1..9) if magic is good, 0 if it is not.

#define SPACE_TIME_TO_XYZT( ss, tt )

Initializer: ( (((char)(ss)) & 0x07) \ | (((char)(tt)) & 0x38) )
